Lub ntsiab txhais ntawm hluav taws qauv evolved mus rau "qhov pom lossis ntsuas lub cev hloov pauv, lossis cov duab txheeb xyuas tau, tsim los ntawm hluav taws cov nyhuv los yog pawg ntawm hluav taws cov teebmeem” (NFPA 2008). Lub ntsiab txhais ntawm hluav taws Cov teebmeem tau los ua "kev hloov pauv tau los yog ntsuas tau hauv lossis ntawm cov khoom siv raws li qhov tshwm sim ntawm a hluav taws ” (NFPA 2008).
Tsis tas li ntawd, tus qauv twg yog hluav taws kub?
Raws li cov khoom yog rhuab thiab lub hluav taws yog pib, convection ua rau lub hluav taws rau hlawv upward thiab sab nraud feem ntau ua rau "V" zoo li char qauv ntawm cov ntaub ntawv nyob ib puag ncig. Cov hluav taws yuav txuas ntxiv mus hlawv upward thiab sab nraud kom txog rau thaum nws ua tau raws li kev tiv thaiv, xws li lub qab nthab.
Cov kws tshawb nrhiav hluav taws pib lawv qhov kev tshawb nrhiav dab tsi? Cov kws tshawb nrhiav siv kev sib xyaw ua ke ntawm kev ua txhaum cai kev tshawb nrhiav , xam phaj, thiab nug cov tswv yim thiab kev paub txog hluav taws science los soj ntsuam scenes. Lawv nrhiav pov thawj ntawm kev siv cov accelerants, xws li roj av thiab lwm yam khoom siv hluav taws xob, thiab ua haujlwm los txheeb xyuas qhov chaw, qhov chaw pib thiab kev sib kis. hluav taws kub.
Tsis tas li ntawd, dab tsi yog lub ncuav mog qab zib?
" Ncuav cov qauv "yuav tsum xa mus rau lub cev ntawm ib yam dab tsi zoo li roj av uas tau siv los pib hluav taws hauv qee lub tsev. Cov neeg tshawb nrhiav hluav taws feem ntau nrhiav cov cim zoo li no thaum lawv sim txiav txim siab seb qhov hluav taws kub puas tau pib txhob txwm ua.
Kev tshawb nrhiav hluav taws thiab hluav taws kub yog dab tsi?
Kev Tshawb Fawb Hluav Taws Xob thiab Hluav Taws Xob . Kev piav qhia. Hluav taws thiab hlawv cov kws tshawb nrhiav tshuaj xyuas lub cev yam ntxwv ntawm a hluav taws scene thiab txheeb xyuas thiab sau cov pov thawj ntawm lub cev los ntawm qhov chaw. Cov pov thawj no yog tom qab ntawd txheeb xyuas los pab txiav txim seb qhov ua rau ntawm qhov hluav taws yog txhob txwm los yog txhob txwm.
